Individual installation procedure

SDT 7.5 is compatible with MATLAB 2018a (9.4) to 2024a (24.1). For earlier SDT see compatibility chart.

Currently compiled platforms are Windows (mexw64), Linux (mexa64).

For install

1. download www.sdtools.com/distrib/sdt75.zip
2. Unzip to a temporary directory (no accents accepted in the name)
3. In MATLAB go to the temporary directory and run sdtcheck sitereq to generate a license request as detailed in www.sdtools.com/help/lic.html
You will need to select products as below and email the request to request@sdtools.com



4. Save the sdt.lic file which you will receive by email in the same directory.
5. Install using sdtkey install .
   You may define a local variable target=’mydir’ to specify a non default location for your SDT.
   
• If you want to preserve a previous copy of the SDT rename the $matlabroot/toolbox/sdt directory.
  
• Start MATLAB, as a user who has write permission on the matlabroot directory (Administrator for Windows, root for UNIX systems).
• If you do not have write permission, see the server procedure to install on another directory.
  
• Within MATLAB, change your current directory to wherever you downloaded the distribution, and run the distribution file

    cd /tmp % or wherever you unzipped the files
    % target='my_dir_location' % you may define the target here
    sdtkey install

• Check that the target directories are correct.
  
  
  
  
  
• When ready press the Install button. Install extracts the proper files, checks the configuration of your installation of the SDT and edits toolbox/local/pathdef.m file so that the SDT becomes included in your default matlabpath.

If you want to preserve a previous copy of the SDT rename the $matlabroot/toolbox/sdt directory.

For upgrade from an earlier version above 7.2, you can now simply run sdtcheck patchupgrade For earlier SDT versions, you need to reinstall.

Multiple SDT or MATLAB installations

• If you have multiple installations (various versions of SDT or a single SDT for multiple MATLAB), you should use a dynamic path generation rather than the default editing of pathdef.m. This is in particular necessary with multiple MATLAB versions since the path order changes. In your startup.m (see doc startup in MATLAB) simply place the lines

   pw0=pwd; cd('my_sdt_location'); % the SDT you want to use
   % cd(fullfile(matlabroot,'toolbox','sdt')) % is default
   sdtcheck('path'); 
   cd(pw0); clear pw0

• To create multiple SDT installations, install using

    SDT_license_key=sdtdef('key'); % use your previous key
    sdtcheck('PathNone'); % clean paths of unused SDT
    cd /tmp % or wherever you downloaded sdt*_dis
    target='my_dir_location' % define the new target
    %target=fullfile(matlabroot,'toolbox','my_other_sdt');
    sdtkey install
    rehash toolboxreset % force clean the toolbox cache

  and use the step above to switch between installations

Admin/write permission problems

The default location fullfile(matlabroot,'toolbox','sdt') is typically protected by admin rights. If you do not have them,

• Install elsewhere

   cd /tmp % or wherever you extracted sdt75.zip
   target='xxx' % select your target directory (cannot be the unzip directory)
   sdtkey install

• Set SDT path by adding to your startup.m file

   pw0=pwd;
   cd('target') % Replace target by the correct location
   sdtcheck('path');cd(pw0);clear pw0

• To edit the default MATLAB path without adding a startup.m, run sdtcheck('path') then open the File:Set path ... menu and click Save. This edits the pathdef.m which, in a normal installation, is performed using sdtcheck('check') which requires write access.
• To make the toolbox available to all users, ask your administrator to copy the target directory to $MATLABROOT/toolbox/sdt directory. On UNIX this is done with

   # edit these lines to appropriate values ####
   setenv MATLABROOT /usr/local/matlab 
   setenv SDT ~/sdt
  
   cp -R $SDT $MATLABROOT/toolbox/sdt
   chmod -R a+rX $MATLABROOT/toolbox/sdt
   chmod -R a+x  $MATLABROOT/toolbox/sdt/*.mex*
